Prostate cancer is the third most common cancer in man.
About 1 in 6 males developed prostate cancer and 1 in 35 males die of this disease. Prostate cancer behavior ranges from microscopic tumors to aggressive cancer with metastatic potential. While metastasis to bone is relatively common, prostate cancer rarely metastasizes to the cecum, pituitary gland, small bowel, maxillary sinus and skin. Our case report presents a rare presentation of metastatic prostate cancer to the duodenum. Our search of the literature found only 2 cases of prostate metastases to duodenum published from 1966 to the present. To our knowledge this is the third case of metastatic prostate cancer presenting with duodenal metastasis. Although it is rare but in symptomatic patients small intestine metastasis should not be ignored with advanced prostate cancer. The case demonstrates a novel presentation of a common malignancy, and should raise awareness in clinicians and radiologists that prostate cancer can present with distant metastases in absence of any local lymphadenopathy.
